The average tidal volume range in an individual with no pulmonary problems is which of the fol-lowing?
 
  a. 4-5 mL/kg IBW
  b. 5-8 mL/kg IBW
  c. 8-10 mL/kg IBW
  d. 12-15 mL/kg IBW

Question 2

A patient in the ICU has a chest X-ray that shows bilateral infiltrates and has the following he-modynamic measurements:
 
  : central venous pressure (CVP) 3 mm Hg, pulmonary artery pressure (PAP) 21/10 mm Hg, and pulmonary artery occlusion pressure (PAOP) 8 mm Hg. These findings are consistent with which of the following?
  a. Acute respiratory distress syndrome
  b. Cardiogenic pulmonary edema
  c. Pulmonary hypertension
  d. Right heart failure

Answer to Question 1

ANS: B
Recommended guidelines are to target the VT to 5-8 mL/kg ideal body weight (IBW) while en-suring that the plateau pressure (Pplateau) is maintained at less than 30 cm H2O.

Answer to Question 2

ANS: A
The central venous pressure (CVP) and pulmonary artery pressure (PAP) are both within normal limits. Therefore, there is no pulmonary hypertension and no right ventricular failure. The bilateral infiltrates with a normal pulmonary artery occlusion pressure (PAOP) do not suggest cardiogenic pulmonary edema but are indicative of acute respiratory distress syndrome (ARDS).

YES! Correct, THANKS for helping me on my review
